Open Source Python Debuggers - Page 3

PyDbgExt is a WinDbg extention which support use Python script in WinDbg command line. Through this extention, we can call some predefine Python script to control the debug session, or directly evaluate expression or call other method.

PySnooper is a simple yet powerful Python debugging utility. Just add a @pysnooper.snoop() decorator, and it logs line-by-line execution with timestamps and local variable tracking—saving you from inserting print() statements manually.

pyringe is a powerful Python process “syringe” that attaches to a running interpreter and lets you introspect—and even execute code inside—that live process. It blends debugger-style attachment (via gdb/ptrace techniques) with Python-aware helpers so you can inspect threads, frames, locals, and heap objects without restarting the target. This is invaluable for post-mortem diagnosis of production daemons where reproducing a bug in a dev shell is impractical. pyringe can inject arbitrary Python into the target process, enabling on-the-spot logging, state dumps, or gentle patching to keep a system limping along while you gather evidence. It’s also useful for forensic snapshots: enumerate objects of a certain type, find reference cycles, or measure memory pressure without pre-instrumentation. While powerful, it’s designed for careful, auditable use—showing exactly what code runs and where—so teams can regain visibility when black-box processes go sideways.

This module goal is to make the debugging tool of python shell even better. By replacing a few methods in the sys module. Standard error traceback are more powerfull with bettererror.py.

Quercitools has just one tool for now - stackcheck.py. It helps in troubleshooting of stack overruns. Such defects destroy stack contents and locating the source of the problem is not easy. This is where stackcheck.py comes to help. It runs a program under test by gdb and protects some parts of the stack. If the program overwrites such parts stackcheck.py stops the program and points to the offending line of code.

RapidGDB is a scriptable GUI for the GDB debugger. Almost every aspect of the program can be extended using Python code snippets.

Desktop interface and various language API's for remote application debugging. The main goal is to provide a better debug system for web languages like PHP. Always download the latest from remotedebugsys folder and the needed API folder.

Soto is a graphical message debugger for simpleIPC. In addition to displaying the message traffic between processes, it can log and play back this traffic. Soto also provides the ability to design GUI "panes" that are populated with data from messages.

Existing libraries implement automatic differentiation by tracing a program's execution (at runtime, like PyTorch) or by staging out a dynamic data-flow graph and then differentiating the graph (ahead-of-time, like TensorFlow). In contrast, Tangent performs ahead-of-time autodiff on the Python source code itself, and produces Python source code as its output. Tangent fills a unique location in the space of machine learning tools. As a result, you can finally read your automatic derivative code just like the rest of your program. Tangent is useful to researchers and students who not only want to write their models in Python, but also read and debug automatically-generated derivative code without sacrificing speed and flexibility. Tangent works on a large and growing subset of Python, provides extra autodiff features other Python ML libraries don't have, has reasonable performance, and is compatible with TensorFlow and NumPy.

Through Browser Debugger (TBD) is a debugger for the Python language which uses any web browser as the user interface. Simply run TBD with the name of the application to debug and your browser will open automatically to display the debugger.

URDB is a universal reversible debugger that adds reversibility to almost any debugger through a python-based wrapper. It also supports reversible debugging of distributed computations, and temporal search on expression values.

A mini cross-platform IDE to cooperate with GCC, GDB, VIM. Programming Language: Python, Vim script. OS: OS independent. Graphics libraries: Use just vim native UI functions.

vimspector is a powerful debugging plugin for Vim and Neovim designed to bring IDE-style debugging capabilities (breakpoints, stepping, call stacks, watch windows) into the modal editor world. It supports multiple languages (C++, Python, TCL among others) via the Debug Adapter Protocol (DAP) model and provides an in-editor UI for viewing scopes, variables, stack frames, output windows and more. You configure it per-project via a .vimspector.json file (or per file type) specifying the adapter, launch configuration or attach process. Once configured you can run, pause, step into/out/over, set and clear breakpoints and inspect variables directly in Vim splits or floating windows. The UI is heavy compared to typical Vim plugins (multiple panes, layouts) but it fills the gap for users who want an integrated debug workflow without leaving the editor.

This tool provides the same interface as a SiteErrorLog but provides the ability to specify who should receive error emails, what error emails are sent, and extra information to put in the headers of the error emails to provide easier mail filtering.

binaryfinary is a binary file format viewer/editor. Profiles are written which describe binary file formats e.g. media files formats, TCP packets, compression formats. Binaryfinary provides an XML-DTD so that these templates can be described in XML.

A collection of pretty printers for GDB 7.x for various boost types.

jbytecode is a Java bytecode disassembler/assembler written in Python. Dissasembly code is aligned with Java bytecodes in the class file so modification and re-assembly is always possible, even when class is obfuscated.

An open plugin providing a full Python Debugging graphical interface and shell for either JEDIT editor or NETBEANS ide. Python\'s debugger backend is implemented as a networking debugger inheriting the standard dbd.py python debugging kernel ,frontend

l3lang is a persistent Python-like language and the l3gui provides a worksheet-like interface where computed values can be examined via simple selection and scripts can be assembled as structures.

Probe the insides of your Brainfuck code

GUI wrapper for the application 'bdisetup' of Abatron. This application is used for configuring their JTAG debuggers, like the BDI2000.

A Python logging library. Straightaway, it does: File and database logging, rotation, remote logging and email notification; stack logging and call hierarchy visualization as debug features.
